Grammy Award-winning a capella vocal artists Pentatonix will return to NBC for their second holiday special. A Very Pentatonix Christmasis set for Monday, Nov. 27 at 10 PM ET/PT on NBC, with an encore airing on Wednesday, Dec. 6 at 8 p.m.

The one-hour show will feature The Voice coach and fellow Grammy-winner Jennifer Hudson joining for some favorite holiday tunes. Also appearing are comedian and former Tonight Show host Jay Leno and 13-year-old America’s Got Talent winner and ventriloquist Darci Lynne Farmer.

Pentatonix today released a new, deluxe version of its 2016 platinum album, A Pentatonix Christmas Deluxe, and will start a Christmas tour on Dec. 3. The group has sold more than 6.4 million albums in the U.S. alone, won three Grammy Awards, and received a Daytime Emmy nomination.
